Donegal Town was the seat of the O'Donnell's up until the
17th Century. The remains of "Donegal Castle" have been restored
and are now a very popular visitor attraction.

The town is also the home of Donegal tweed industry
in Ireland and the Magee brand name has become world-renowned and famous for
Donegal Tweed.

In the centre of the Diamond you can view a tall
obelisk dedicated to the memory of the Four Masters. This was the name given
to the four friars, who in the 17th century complied the Annals of the Four
Masters, one of the earliest historical texts recording the early history of
Ireland.

A short stroll from the Diamond is the old harbour area over looking the
famous Donegal Bay from where you can climb aboard the Donegal Bay Waterbus
and enjoy the magnificent views while listening to the onboard commentary on
the history of Donegal Town.
